Laser Photocoagulation and Cryopexy for Retinal Tears

Topic Overview

Laser photocoagulation and cryopexy are used to fix tears
in the
retina and prevent a
retinal detachment. These
methods work well to treat certain retinal tears. But some people will need
future treatment for a tear in another part of the retina.

You can usually receive these treatments in a doctor's office or an
outpatient surgery center. They do not require a
hospital stay or
general anesthesia. You may need to limit your activity for a couple of weeks after treatment.

In laser photocoagulation, an intense beam of light travels
through the eye and makes tiny burns around the tear in the retina. Over
several weeks the burns form scars that prevent fluid from getting under the
retina.

Cryopexy
achieves the same result by using a probe to freeze and seal the retina around
the tear.

Both
methods keep fluid in the middle of the eye from passing through the retinal
tear. If fluid gets under the retina, the retina can detach from the wall of the eye.

If you need retinal detachment surgery and you have a torn retina, these same methods are used to seal the tear in the retina.
